Finding Nemo (2003)

Nemo, an adventurous young clownfish, is unexpectedly taken from his Great Barrier Reef home to a dentist’s office aquarium. It’s up to his worrisome father Marlin and a friendly but forgetful fish Dory to bring Nemo home — meeting vegetarian sharks, surfer dude turtles, hypnotic jellyfish, hungry seagulls, and more along the way.

A catastrophic volcanic eruption releases ancient dragon-like creatures on the surrounding areas. Scientists believe this could start a chain reaction of volcanic eruptions giving way to a global Dragon Apocalypse.
